Mechanical stop arrangement for a borehole tubular to locate and restrain a borehole tool to an outside diameter of the tubular, method, and system

Abstract

A mechanical stop arrangement includes a first coupler having a tool connection segment, and an arrangement connection segment, a second coupler having a first connection segment connectable with the arrangement connection section, and a frustoconical inside diameter surface, and a wedge having a radially outside surface angle that is complementary to the frustoconical inside diameter surface. A method for connecting a borehole tool to an outside surface of a tubular, including connecting the borehole tool to a first coupler either before or after disposing the coupler on the tubular, disposing the first coupler on the tubular, disposing a wedge on the tubular, disposing a second coupler on the tubular, interconnecting the first coupler and the second coupler, and jamming the wedge against the tubular with the interconnecting. A wellbore system, including a borehole, a string in the borehole, and an arrangement, disposed within or as a part of the string.

What is claimed is: 
     
       1. A mechanical stop arrangement for attachment to a separate borehole tubular in any location along the separate borehole tubular to locate and restrain a borehole tool to an outside diameter of the separate borehole tubular, the separate borehole tubular extending past each of two longitudinal ends of the arrangement, comprising:
 a first coupler dimensioned and configured to be disposed about the separate borehole tubular and having a clearance fit around the separate borehole tubular, the first coupler having:
 a tool connection segment configured to connect with a downhole tool; and 
 an arrangement connection segment; 
 
 a second coupler dimensioned and configured to be disposed about the separate borehole tubular and having:
 a first connection segment connectable with the arrangement connection section; and 
 a frustoconical inside diameter surface; and 
 a wedge having a radially outside surface angle that is complementary to the frustoconical inside diameter surface. 
 
 
     
     
       2. The arrangement as claimed in  claim 1 , further comprising a seal disposable between the first coupler and second coupler and configured and dimensioned to create a seal against the tubular, when the arrangement is in use. 
     
     
       3. The arrangement as claimed in  claim 2 , wherein the seal is in contact with the wedge, the second coupler and the first coupler and subject to compression by the arrangement. 
     
     
       4. The arrangement as claimed in  claim 1 , wherein the wedge also creates a seal. 
     
     
       5. The arrangement as claimed in  claim 4 , wherein the seal is metal to metal. 
     
     
       6. The arrangement as claimed in  claim 4 , wherein the wedge includes a sealing material coating. 
     
     
       7. The arrangement as claimed in  claim 1 , wherein the wedge is a ring. 
     
     
       8. The arrangement as claimed in  claim 1 , wherein the wedge is a split ring. 
     
     
       9. The arrangement as claimed in  claim 1 , wherein the wedge is a plurality of wedges arranged about the tubular when in use. 
     
     
       10. The arrangement as claimed in  claim 1 , wherein the wedge includes a surface texture. 
     
     
       11. The arrangement as claimed in  claim 10 , wherein the surface texture is teeth. 
     
     
       12. The arrangement as claimed in  claim 1 , wherein the surface angle is in a range of about 3 degrees to about 15 degrees from a longitudinal axis of the arrangement. 
     
     
       13. The arrangement as claimed in  claim 1 , wherein the surface angle is in a range of about 3 degrees to about 5 degrees from a longitudinal axis of the arrangement. 
     
     
       14. The arrangement as claimed in  claim 1 , wherein the borehole tool is an inflow control tool. 
     
     
       15. The arrangement as claimed in  claim 1 , wherein the borehole tool is a liner hanger. 
     
     
       16. The arrangement as claimed in  claim 1 , wherein the borehole tool is a packer. 
     
     
       17. The arrangement as claimed in  claim 1 , wherein the borehole tool is electronics. 
     
     
       18. The arrangement as claimed in  claim 1  wherein the borehole tool creates a chamber. 
     
     
       19. The arrangement as claimed in  claim 18  wherein the chamber is sealed from wellbore fluids. 
     
     
       20. A wellbore system, comprising:
 a borehole in a subsurface formation; 
 a string in the borehole; and 
 an arrangement as claimed in  claim 1 , disposed within or as a part of the string. 
 
     
     
       21. A method for connecting a borehole tool to an outside surface of a separate tubular, comprising:
 connecting the borehole tool to a first coupler either before or after disposing the coupler on only an outside surface of the separate tubular; 
 disposing the first coupler on the separate tubular; 
 disposing a wedge on the separate tubular; 
 disposing a second coupler on the separate tubular; 
 interconnecting the first coupler and the second coupler; and 
 jamming the wedge against the separate tubular with the interconnecting. 
 
     
     
       22. The method as claimed in  claim 21 , further comprising energizing a seal disposed between the first and second couplers to create a seal against the tubular.
